A review of intentional electromagnetic interference in power electronics: Conducted and radiated susceptibility

Abstract

With the advancements in Industry 4.0 and the global demand for sustainable energy, power electronics devices are emerging as pivotal components for modern industrial, transportation, and energy delivery. Ensuring the security of these devices is of paramount importance for safeguarding the reliable operation of critical systems against any threats. In recent years, the issue of intentional electromagnetic interference (IEMI) attack and their related countermeasures have gained widespread attention in both military and civilian power electronics sectors. Here, a review of IEMI in power electronics is provided. Starting from the electromagnetic compatibility standards, the test setups for evaluating the device immunity are introduced. Due to different attack modes and propagation paths, IEMI illuminations are typically categorized into conduction and radiation, where their susceptibility studies, applications, and defence strategies are discussed, respectively. Finally, the existing challenges, ongoing trends, and future topics in this field are discussed.

Enhancing motor impedance measurements: broadening the spectrum from low to high frequencies

“…These issues can compromise the motors' reliability and lifespan [9][10][11]. Addressing these problems often requires access to motor impedance information, typically ranging from a few hundred Hz to several tens of MHz [12][13][14]. Acronyms †: SP (Single-phase), PG (Phase-to-ground), CM (Common-mode), DM (Differential-mode), Mag (Magnitude), and Pha (Phase).…”
